To all whom it may 0001007 12 Be it known thatI, FREDERICK H. PERRY, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in -Methods of ChannelingShoe-Soles; and I do hereby declare'the following to; be a full, clear, and exact'description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. 7 I

The invention relates to a method of channeling shoe soles, and to the sole channeled thereby.

This application is a division of application Serial N 0. 122,004, filed September 25, 1916.

It has been customary in channeling the outsoles of shoes to cut the channel a uniform depth throughout, and at a greater distance from the edge of the sole through the shank than about the forepart, the edge of the sole being trimmed or chamfered off up to the edge of the channel flap in finishing the shoe after the outsole has been sewed thereto In doing certain classes of work the trimming or chamfering of the edge of the sole along the shank is objectionable. For instance, in making shoes having thin edge shanksin which the sole edge is reduced in thickness by skiving the outsole outside the bottom of the channel through the shank, the subsequent trimming of the sole edge tends to nullify the effect of the skiving.

It is the primary object of the present invention to so channel thesole that comparatively little'cutting away or trimming of its edge will be required in the edge finishing operations. The invention accordingly contemplates cutting a channel of varying depth a uniform distance from the sole edge, the channel being deeper and the channel .flap correspondingly broader through the shank than about the forepart. The bottom of the channel may thus be located at the proper increased distance through the shank, and at the same time a channel flap will be, provided of suflicient breadth to extend substantially. tothe sole edge, so that little trimming is required to finish the sole edge increase the depth after the channel flap is laid. The invention also contemplates skivingor beveling the edge of the sole to form a thin edge shank, and in such case the broad channel fiapis especially important, since it will properly cover the 'outseam, and since the thickness of the skived sole edge need not be materally increased by the subsequent edge finishing operations. I

I The invention as outlined above" is illustrated in the accompanying drawings, in which Figure 1 shows the bottom of an outsole channeled in accordance with the invention, and Fig. 2 is a fragmentary sectional view on line 2 of Fig. '1;

The 'outsole shown in the drawings is provided about its edge with a channel 2 of varying depth, which is out at a uniform distance from the edge of the sole to form a channel flap 4, the width of which varies in accordance with the depth of the channel. Since the bottom of the channel of an out sole should be at a greater distance from the edge ofthe sole through the shank than about the forepart, the channel iscut to a uniform depth about the forepart, and is' cut to an increased depth through the shank. The channel may be out by any suitable means or mechanism, as for instance by the machine shown and described in the application above referred to. If cut on a channeling machine, or on a rounding and channeling machine, the channel knife or knives should be constructed and operated to cut the deep channel and broad channel flap through the shank to decrease the depth of channel and width of channel flap in passing from the shank to the forepart, and to of the channel and breadth of the channel flap in passing from the forepart into the shank at the other side of the sole.

In manufacturing shoes having thin edge shanks, the edge of the sole outside of the bottom of the channel and under the channel flap is cut away or skived to form a bevel edge, as indicated at 6 in Fig. 2. This may be done at the same time the deep channel is cut, or subsequently.

. The above method of channeling the sole provides abroad channel flap through the shank which reaches substantially to the edge of the sole, so that no more trimming is required in finishing the sole" edge through the shank than about the fei epait, and in the 'caee of" it. sole having a skived 01 beveled- 'ed ge,"the -fi-ap is brozid 'enough to reach down over and be securely. cemented t0 the inclined surface ofi the eel e.
